Sever’s Disease

This is a common problem of the heel bone in growing children. It is not really a disease and should not really be named after Dr Sever as there is a trend away from naming conditions after people, so the term calcaneal apophysitis should be the preferred term, however the term ‘Sever’s’ is much more widely used in the search engines.

The team at PodChatLive did a deep dive into Sever’s disease in one of their episodes and it is well worth a watch:

Severs disease is sometime difficult to manage due to a high level of a lack of compliance with the kids to advice to cut back on activity levels. Load management, lifestyle changes and education about expectations are key to managing this condition so getting the compliance of the child really is important. A cushioned heel pad is also often used to help protect the heel.

The natural history of Severs disease is to get better on its own if the loads are management and normal growth is allowed to occur. All cases are gone by the mid-teenage years. What this means is that the best strategy is to manage the loads and the pain and wait for it to heel up.

Chilblains really are a relatively common problem if the weather is cooler. These are a painful and itchy reaction of the smaller arteries in the toes to the changes in temperature. They lead to a painful red patch, that later becomes a dark blue color should they become chronic. They have lately been receiving some extra coverage from the mass media because of them being more common in individuals infected with the coronovirus, getting the label, COVID toes.

Chilblains are a seasonal problem and appear in all places in which the environment will get cold enough to result in the reaction in the skin. An episode of PodChatLive had a comprehensive discussion of the condition of chilblains:

The simplest way to deal with chilblains is to prevent these by keeping the feet warm. If a chilblain does occur then it needs to be kept warm and be protected to stop the skin from breaking down. There are several chilblain creams which can be used to help to promote the blood flow.

Can a plantar plate tear heal on it own?

A plantar plate tear is a strain or small tear of the ligament (plantar plate) that is plantar to the metatarsophalangeal joints in the ball of the foot. the pain is typically plantar and distal to the joint. You often see it being asked in forums and on message boards if is it possible for a plantar plate to heel with any specific treatment.

Unfortunately, it is highly unlikely that a plantar plate tear will heal on its own without some form of intervention. The symptoms in the plantar plate from a tear or a “pre-tear” (dysfunction) are due to a mechanical overload. If that overload is still there, then it is probably not going to heal up on its own. However, if you limp and reduce activity levels, then that mechanical overload is reduced so it might heal up on its own, eventually.

The use of taping to hold the toe plantarflexed to reduce the mechanical overload by preventing the toe from dorsiflexing can certainly give it time to heal. Is that healing on its own? Probably not as the strapping is a treatment, so that is technically not healing on its own. That is how you do get it to heal up; you use strategies like the strapping, like stiff-soled or rocker sole shoes or foot orthotics to off-load that mechanical overload to allow it to heal.

Do Bunion Correctors Help

Bunion correctors are getting a lot of promotion online, but they have been around for a very long time.

The question often asked, do they work? The evidence is that they can help improve the angle of the hallux by a few degrees after a month of using them at night. That may or may not be worth the effort.

There is a lot of fake marketing of these, so please do not fall for the fake before and after photos or the made up testimonials.

100 Up Running Drill

The 100 Up Running drill is a rill that was recently rediscovered to help runners improve their running technique. This eBook covers the technique in detail and how to carry it out:

From the Publisher:

The ‘100-Up’ Exercise was devised in the nineteenth century by runner and athlete, Walter G George. The technique had become almost forgotten, until a New York Times article by Christopher McDougall revived interest in the exercise amongst twenty first century runners eager to improve their performance.

This short eBook takes a fresh look at how the ‘100-Up’ method began and includes full instructions on how you can implement the exercise yourself.

The beauty of the ‘100-Up’ Exercise is that it can be used by almost anyone to develop fitness and stamina. For serious runners, it’s a way to improve technique, but the ‘100-Up’ method can also be used by non-athletes. Best of all, it’s an exercise you can do indoors or outdoors, at home or at work… in fact, almost anywhere.

The Science of Footwear

The Science of Footwear
Editor: Ravindra S. Goonetilleke

Hardcover; 726 pages; 1st edition; 2012

Book Description
Although we now have sophisticated algorithms and techniques for determining the shapes and sizes and for matching the fit between shoes and feet, few, if any, of the books currently available cover these new technologies until now. Bringing together high-quality and state-of-the-art contributions from designers, biomechanists, ergonomists, engineers, podiatrists, and scientists from industry and academia, The Science of Footwear provides an in-depth understanding of the technology and techniques involved in the design and development of a popular and demanding consumer product.

This book introduces the design, development, manufacturing, and marketing of footwear. The chapters contain data from past research and the state-of-the art methodologies. They not only cover every aspect of the product design, but also how the footwear industry caters to the wide-ranging needs of sophisticated and demanding customers.

The footwear industry has rapidly changed over the last 10 years. Mass production has changed to personalization and mass customization, areas that are not well-understood. This book explores these different concepts in a coherent way, drawing on differing views that give a holistic view of the science behind footwear. Collating information from different disciplines, the book provides the tools to develop the next generation of footwear

Chi Marathon: The Breakthrough Natural Running Program for a Pain-Free Half Marathon and Marathon

The Breakthrough Natural Running Program for a Pain-Free Half Marathon and Marathon

Authors: Danny Dreyer, Katherine Dreyer

Format: Paperback
Pages: 292
Published: March 2012

Publisher Info:
From the authors of the bestselling “Chi Running” comes a game-changing training guide for injury-free long distance running.
In Chi Marathon, Danny Dreyer, creator of the revolutionary ChiRunning program, highly respected running coach, and accomplished distance runner, takes a whole-body approach to long-distance running—much like T’ai Chi—making ease and efficiency of movement the prime goal of one’s training. Chi Marathon is the first book to focus not on building stamina first (though that is covered here) but on how to run all those miles without harming your body. A staggering 80 to 90 percent of marathoners face injuries during their training. This book debunks the myth that marathoners need to push through and beyond pain, and presents a technique-based plan for pain- and injury-free, high-performance half and full marathons. Chi Marathon also shows how to improve your performance by developing your own race-specific training plan tailored to your event, and will help you cross the finish line feeling strong no matter your age, body type, or running ability.

Reviews of Chi Marathon:
“The Dryers don’t believe in “no pain, no gain” for runners. Instead, their holistic approach is a smarter and healthier way for runners to fully develop balanced body mechanics for an injury-free life. The old school, conventional running trends have created too much ill-health and pain for all athletes, but “Chi Marathon” changes all that. Regardless of your age and experience, you’ll learn how to run efficiently from head to toe. The result is more enjoyable, and you will now finish marathons and other endurance races feeling refreshed rather than wasted.” –Dr. Philip Maffetone, author of “The Big Book of Endurance Training and Racing”
